    摘要： On substrates 2a, 2b of a chiral nematic liquid crystal optical element 1, transparent electrodes 3a, 3b and electrical insulation layers 4a, 4b are formed, and further, resin layers 5a, 5b having a pencil hardness of “B” or less are formed on the electrical insulation layers by a spin coating method so as to be in contact with a liquid crystal layer 7. When the surface hardness of the resin layers is to be measured, a glass substrate on which a resin layer is formed by screen-printing is prepared as a test piece, and the test piece is fitted to a pencil-scratching tester. The surface hardness is measured by scratching the test piece with two kinds of testing pencil selected from testing pencils having 17 grades of density.

    摘要： To a bifunctional acrylurethane compound having acrylate groups at its both ends, which is a reaction product of polypropylene glycol, a mixture of 2,2,4-trimethyl-1, 6-diisocyanatohexane and 2,4,4-trimethy1-1, 6-diisocyanatohexane, and 2-hydroxyethyl acrylate, 2-ethylhexyl acrylate, 2-hydroxyethyl acrylate, nematic liquid crystal and a photo-reaction initiator are mixed to obtain a uniformly dissolved mixture, and the mixture undergoes a phase separation treatment by photopolymerization to thereby form a liquid crystal/polymer composite material layer 7 which is utilized for a liquid crystal optical element 1. The phase separation by photo-polymerization improves controllability of the structure of the liquid crystal/polymer composite material layer. In particular, the shape of the polymer phase with respect to the liquid crystal phase is precisely controlled to adjust the optical characteristic performance of liquid crystal domains in a connected phase of liquid crystal; to improve the electro-optical characteristics in a low temperature region, and to obtain a display of high contrast and low hysteresis.
